序 1927年完成了第一次铅同位素分析(Aston 1927),而理论上的研究工作则在1940年前就已经进行(Nier 1938)。历史已经证明,基础学科的多数成果必然会找到经济上的应用。近年来已经出现这样的迹象,尽管还不成熟,铅同位素的研究正在越出学术的和发展惯例的范围,而在矿产远景评价领域内得到应用。铅同位素的研 The first lead isotope analysis was completed in 1927 (Aston 1927), and the theoretical work was done before 1940 (Nier 1938). History has proven that most of the achievements of the basic disciplines are bound to find economic applications. In recent years, there have been some indications that, although not yet mature, the research on lead isotopes is going beyond the scope of academic and developmental practices and applied in the field of mineral prospecting.
